    LONDON－Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets (彗星) in the direction of Earth, and its orbit will be changed too. Our world will then be sent spinning into a safer, colder part of the solar system.

    This idea for improving our climate comes from a group of U. S. National Aeronautics and Space Administration (NASA) engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet－effectively doubling its working life.

    The plan put forward by Dr. Laughlin, and his colleagues Don Korycansky and Fred Adams, needs carefully directing a comet or asteroid so that it passes close by our planet and sends some of its gravitational energy to Earth.

    “Earth's orbital speed would increase as a result and we would move to a higher orbit away from the Sun,” Laughlin said.

    Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.

    In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The Sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere (生物圈) －by cooking us.

    That's why the group decided to try to save Earth.

    The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation (误算) in orbit could fire it straight at Earth--with deadly consequences.

    There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position, it is “most likely the Moon would be stripped away from Earth”. This would greatly change our planet's climate.

    Mr. Peter Johnson, aged twenty- three, battled for half an hour to escape from his trapped car yesterday when it landed upside down in three feet of water. Mr. Johnson took the only escape route—through the boot (行李箱).

    Mr. Johnson's car had finished up in a ditch (沟渠) at Romney Marsin, Kent, after skidding on ice and hitting a bank. "Fortunately, the water began to come in only slowly," Mr. Johnson said. "I couldn't force the doors because they were jammed against the walls of the ditch and dared not open the windows because I knew water would come flooding in."

    Mr. Johnson, a sweet salesman of Sitting Home, Kent, first tried to attract the attention of other motorists by sounding the horn and hammering on the roof and boot. Then he began his struggle to escape.

    Later he said, "It was really a half penny that saved my life. It was the only coin I had in my pocket and I used it to unscrew the back seat to get into the boot. I hammered desperately with a hammer trying to make someone hear, but no help came."

    It took ten minutes to unscrew the seat, and a further five minutes to clear the sweet samples from the boot. Then Mr. Johnson found a wrench (扳手) and began to work on the boot lock. Fifteen minutes passed by. "It was the only chance I had. Finally it gave, but as soon as I moved the boot lid, the water and mud poured in. I forced the lid down into the mud and scrambled clear as the car filled up."

    His hands and arms cut and bruised，Mr. Johnson got to Beckett Farm nearby, where he was looked after by the farmer's wife, Mrs. Lucy Bates. Trembling in a blanket, he said, "That thirty minutes seemed like hours." Only the tips of the car wheels were visible, police said last night. The vehicle had sunk into two feet of mud at the bottom of the ditch.

    The American Heart Association (AHA) says that too many people are spending far too much time on chairs and couches. "Based on existing evidence, we found that U.S. adults are sedentary for about six to eight hours a day, "said Deborah Rohm Young, chair of AHA panel that wrote the new advisory.

    According to the AHA, growing evidence shows that, on its own, exercise isn't enough to cancel out the unhealthy effects of sitting for a long time. "Regardless of how much physical activity someone gets, long sedentary time could negatively influence the health of your heart and blood vessels," Young explained.

    The exact mechanisms behind the effect aren't yet clear. “There are many important factors we don't understand about sedentary time yet," Young said. She stressed that, "the types of studies available identify trends but don't prove cause and effect.”

    "We don't have information about how much sedentary behavior is bad for health — the best advice at this time is to 'sit less and move more,” she added.

    How much more? According to the AHA, people should try to get at least 30 minutes of moderate to vigorous (剧烈的）exercise a day to reach the recommended 150 minutes of moderate exercise or 75 minutes of vigorous exercise a week, That's healthier than trying to cram their weekly exercise into one or two days, according to the statement.

    "The real risk simply comes down to the amount we sit, without there being a true medicine or method to control the harmful effects," said Steinbaum, a preventive specialist in heart disease.

    Still, society has evolved to encourage sitting, she added.

    "Our lives have become focused around activities requiring us to be still—whether it be transportation, our computers, or the television or computer in our leisure time,” Steinbaum said. "Sociologically, instead of being active to be productive or to have enjoyment, our productivity and fun often requires minimal physical activities."

    Don't miss the 3rd annual Family Fun Fair!

    This fair promises to be even better than last year's fair—no kidding!

    Last year the game booths (摊位) were a big hit. (Who could forget Principal Snyder winning a toy dog that was so big it took four students to carry it to her truck?) This year we have two new game booths. So get ready to take part in the games.

    Visit our craft tables. They will be better than ever! You can buy items such as clothing, backpacks, and gift baskets.

    Children aged 5 and under can have their faces painted for FREE by Mr. Garcia's third-grade art class.

    No fair would be complete without food. We will be selling hot dogs, ice cream, roasted nuts, and cotton candy at our booths. For those of you who love to bake, why not enter our new apple pie contest? Just bring your pie to the pie table on the morning of the fair. At 1 p. m., our judges, Coach Carter and math teacher, Mrs. Adams, will choose a winner.

    Won't you please support our school by coming to the fair? Tickets are only $2 each. Door prizes will be given. You could win sports equipment, a new camera, or dinner for four at Merino's Restaurant!

    This will be the best fair ever. Don't miss it!

    At 23 I applied for full-time positions with no intention of working five days a week. As a housewife, I had two pre-school children then but wanted to work three days a week.

    This was a huge deal for me. I needed to work, but also wanted to spend time with my children while they were young. I didn't want to miss out on school drop-offs and pick-ups. But I also didn't want to miss out on the opportunity of promotion.

    Before the interviews, I prepared a plan of how I was going to make this work for me and the employer. I saw it as a two-way agreement — the business adapting to me and me adapting to the business.

    Finally I became a member of EY at 33. EY was the only firm that seemed receptive to my plan; in fact, we spent time during that first interview talking about how we could make it work together. Most importantly, the person interviewing me worked flexibly too — four days a week.

    I appreciated that I'm one of the lucky ones. Even 10 years on, flexible hiring and working remains the exception rather than the rule for most.

    What will help shift views and behavior, in addition to organizations updating their hiring policies, is talking more openly about how most of us organize our day around our responsibilities. We all have a life outside of work and we shouldn't be embarrassed to talk about it, even during a job interview.

    It's a change in the way of thinking, not just for employers but employees too. In the early days I was confident about my ability but I probably did have a preconception (先入之见) that working part-time would limit my career progression. What I quickly realized was that if I took responsibility for my development, I could make sure that I got the same opportunities as if I was working full-time. So I offered solutions to how we could make it work, and it made me stand out.
